Nick Lachey and Vanessa Minnillo 'Mini-Moon' in St. Barts

A week after Nick Lachey and Vanessa Minnillo tied the knot on Necker Island – Sir Richard Branson's private oasis in the British Virgin Islands – the couple are honeymooning in St. Barts.
Hot bodies on display, Lachey, 37, and Minnillo, 30, cooled off in the ocean Thursday.
"We just wanted something relaxing," Lachey tells PEOPLE. "We weren't necessarily able to take our dream honeymoon because of timing, but we'll take this mini-moon and do that one later."
The Sing-Off host is due back to work within the week, he says, so the newlyweds couldn't take off to their dream destination, the Maldives.
But one thing Lachey isn't complaining about: his wedding day.
"It literally took my breath away," Lachey told PEOPLE about the moment he saw his bride, dressed in a two-piece Monique Lhuillier ensemble. "It's a moment you fantasize about, and I was certainly not disappointed."
